HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Potentially bad value “Copyright” for attribute “rel” on element “link”: The keyword “copyright” for the “rel” attribute should not be used. Consider using “license” instead.
Empty heading.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The value of attribute “title” on element “a” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Text run is not in Unicode Normalization Form C.
Errors:
Heading cannot be a child of another heading.
Stray end tag “h1”.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
Attribute “wight” not allowed on element “img” at this point.
Attribute “aling” not allowed on element “img” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The element “a” must not appear as a descendant of the “button” element.
Stray end tag “a”.
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
